Resumen

Systemic inflammation is associated with impaired wound healing in diabetes mellitus (DM) patients. Using immunohistochemistry techniques, the authors investigated changes in skin inflammation and skin blood vessels in human and experimental diabetes. Comparing to the non-DM human subjects, the total number of inflammatory cells per biopsy and the number of inflammatory cells around blood vessels, a strong indication of inflammation, were higher in DM subjects irrespective of their risk for developing diabetic foot ulcer. Inflammatory cell infiltration was robustly increased in all DM animal m

Resumen

In this study, we use vibrational optical coherence tomography (VOCT) to examine the morphology and stiffness of benign and cancerous lesions. Lesion images and 3D plots of weighted displacement versus frequency and depth were used to compare the cellular, dermal collagen, new blood vessels, and fibrotic composition of normal skin, actinic keratoses (AK), nodular and superficial basal cell carcinomas (BCCs), squamous cell carcinomas (SCCs), and melanomas. The results of this study suggest that benign and cancerous lesions differ based on the addition of new cells with increased resonant freque

Morphological changes of the dermal blood vessels of moxibustion-stimulated rat skin were examined with reference to the lymphocyte migration. After long-term stimulation with direct moxibustion to the acupoint Tsu-San-Li (St-36), peculiar vessels that possess immunohistological features of high endothelial venules could be observed in the moxa-stimulated acupoint dermis. Endothelial cells of the vessels had well-developed Golgi apparatus in their plump cytoplasms, and they strongly expressed intercellular adhesion molecule-l on the luminal surface.

Resumen

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited small- and medium-artery disease of the brain caused by mutation of the Notch3 gene. Very often, this disease is misdiagnosed. We examined skin biopsies in two members of the first discovered Serbian family affected by CADASIL. Electron microscopy showed that skin blood vessels of both patients contain numerous deposits of granular osmiophilic material (GOM) around vascular smooth muscle cells (VSMCs). We observed degeneration of VSMCs, reorganization of their cytoskeleton and d

Resumen

As a starting point for developing analytical models of predicting skin temperature and damage extent into multi-layer ones, a double-layer model consisting of two distinguished and attached layers is considered: a tissue layer containing blood vessels and a tissue layer containing no blood vessels. The Pennes model is applied for the tissue containing blood vessels. Applying the Laplace transform, then the inversion theorem for Laplace transforms and the Cauchy residue theorem, the desired skin temperature function is obtained.

Resumen

Intraoperative vascular imaging using indocyanine green (ICG) angiography may better predict flap viability than clinical judgement alone. Intraoperative ICG angiography was used in a chronic corticosteroid user undergoing bilateral nipple sparing mastectomy with expander placement. Large blood vessels were visualized, however, the skin surrounding these vessels remained dark. The flap demarcated to full-thickness necrosis that matched the intraoperative SPY findings. Visualization of intact blood vessels may not be sufficient to rule out flap necrosis in some patients. In these circumstances,

Abstract Vasculitis in rheumatoid arthritis (rheumatoid vasculitis, RV) has a heterogeneous clinical presentation that includes skin disorders, neuropathy, eye symptoms and systemic inflammation. Rheumatoid vasculitis is an unusual complication of longstanding, severe rheumatoid arthritis (RA). While RA affects the body’s joints, vasculitis is a condition in which blood vessels become inflamed. Rheumatoid vasculitis occurs in approximately 2 to 5% of patients who have RA. The blood vessels most often involved are arteries that bring blood to the skin, nerves, and internal organs. Veins can als

Resumen

Churg-Strauss syndrome (CSS) is a rare autoimmune vasculitis of unknown etiology that involves small- and medium-sized blood vessels. Its onset is thought to be associated with adult-onset asthma, and vasculitis typically involves vessels in the lungs. However, due to increased blood and tissue eosinophilia, vasculitis may result in the involvement multiple systems of (neurological, skin, etc.). We report a case of CSS with manifestations that included skin purpura and severe peripheral nerve degeneration in a 56-year-old woman with a recent history of asthma.

Finger blood flow (BF) and skin sympathetic nerve activity (SSA) to the glabrous side of the hand were measured during immersion of the hand in a water bath in which temperature (Tw) was raised every 10 min by steps of 2 degrees C from 35 or 37 to 41 degrees C. The experiments were conducted during the summer in rooms in which ambient temperature was 28-32 degrees C or 35 degrees C. The nine healthy male subjects were wearing summer clothes. Finger BF through vessels located deep in the skin was measured by using laser-Doppler flowmetry (ALF-2100, Advance). With the use of a tungsten microelec

AbstractIntroduction. Abnormal angiogenesis is described in tumor growth and it facilitates its metastatic spread. Tumors with high angiogenic activity belong to the category of aggressive tumors with poor prognosis for patients.The aim of this study was to determine the blood vessels density (BVD), i.e. neovascularization at the tumor invasive front in skin squamous cell carcinoma (SCC) in order to determine its possible role in the tumor progression, and to correlate it to the blood vessels density of healthy skin and with the prognostic parameters of the TNM classification: T status, depth

Resumen

Type 2 diabetes (T2D) and ageing have well documented effects on every organ in the body. In T2D the autonomic nervous system is impaired due to damage to neurons, sensory receptors, synapses and the blood vessels. This paper will concentrate on how autonomic impairment alters normal daily activities. Impairments include the response of the blood vessels to heat, sweating, heat transfer, whole body heating, orthostatic intolerance, balance, and gait. Because diabetes is more prevalent in older individuals, the effects of ageing will be examined. Beginning with endothelial dysfunction, blood ve

Resumen

Melanoma, characterized by high mortality, rapid development and accompanied with angiogenesis is the most typical malignant tumor in skin cancer. Hence, the detection of blood vessels is of much significance. The early vascular network has small scale. If we remove the tumor early and biopsy it, it will increase the spread of the cancer cells and infection and bleeding. In this case, we presented a new angiography method. A high-resolution OCT system for noninvasive angiographic imaging of early skin melanoma — Swept Source Optical Coherence Tomography Angiography (SS-OCTA) is proposed. With

Background: Grafts and flaps are commonly used for wound closure which can be caused by trauma, chronic disease, post excision tumors, burns, and infections. Reconstructive can fail because of the poor wound bed, radiation, vascular insufficiency and reperfusion injury (IR). EPA and DHA (omega-3) are new compounds that have a strong effect on controlling inflammation in the resolution phase. Some studies say that EPA and DHA (omega-3) are described not only to lower plasma triglyceride levels but also have anti-inflammatory effects and improve endothelial function, all of which mediate anti-at

Resumen

Background: Dermatoscopy (DS) has been used primarily to evaluate pigmented skin lesions. Little information is available on DS findings of basal cell carcinoma (BCC). Dermatoscopy is a noninvasive technique that allows visualization of cutaneous features from the skin surface to the papillary dermis. Basal cell carcinoma, the most common cutaneous malignancy, is traditionally diagnosed clinically and confirmed with biopsy. Objective: To determine the dermatoscopic features of non-pigmented basal cell carcinomas. Methods: The dermatoscopic findings of 27 lesions that clinically were suspicious
